What is LLM (Large Language Model)?
An LLM is an AI model trained on massive text to predict the next word — the base of ChatGPT, Claude, Gemini and most generative AI products.
LLMs (Large Language Models) use transformer architecture and hundreds of billions of parameters. They don't "reason" like humans: they calculate next-word probability given context. All the "intelligence" emerges from that simple task at scale.
In 2026, frontier LLMs (GPT-4o, Claude 4.7, Gemini 2.5) reach 1M+ context tokens and cost cents per million tokens. Built into nearly every SaaS — those that don't adopt become obsolete.

Frequently asked questions
Is LLM "intelligent" like a human?
No. It is next-word probability. It appears to reason because trained on human text, but lacks real understanding.
Which LLM to choose for my product?
Don't pick just one. Multi-LLM lets you use each where it shines: Claude for writing, GPT for code, Gemini for long context.
